RUNNING-GEAR FOR VEHICLES.

Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed July so, 1907. Serial No. 386,230.

To all whom it may concern:

Be it known that I, ABRAHAM L. HAMIL- TON, a citizen of the UnitedStates, residing at Sugartown, in 'the parish of .Calcasieu and State ofLouisiana, have invented certain new and useful Improvements in Running-Gear for Vehicles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in running gearfor vehicles and consists in the provision of various details ofconstruction and combinations and arrangements of parts which will behereinafter fully described and then specifically defined in theappended claims.

I illustrate my invention in the accompanying drawings, in which IFigure 1 is atop plan view of a running gear embodying the features ofmy invention. Fig. 2 is an enlarged detail perspective'view of thetongue showing the manner of adjustment of the same. view on line '33 ofFig. 1 and Fig. 4 is a central longitudinal sectional view of the poleor tongue and tongue hound.

Reference now being had to the details of the drawings by letter, AAdesignate the wheels of the running gear which are mounted on the frontand rear axles, upon which latter the bolsters B and C are mounted.

D designates the hound which is fastened to the rear axle and isprovided with a centrally disposed metallic shell D adapted to conformto the shape of the reach section E, which is mounted to slidelongitudinally therein, whereby the gear may be made extensible to adaptthe running gear for various purposes. Said shell is provided with anaperture registering with an aperture e in the p ate E and the reachsection E is also provided with apertures E through which apertures inthe shell and reach section and also said plate a pin may be passed inorder to hold the reach section in an adjusted position. Upon the rearaxle of the running gear is a bolster F, preferably covered with ametallic sheathing, and is pivotally mounted upon a pin G which passesthrough registering aper- Fig. 3 is a cross sectional turl'es in therear end of said shell and the rear ax e. I

H designates the forward reach section which is pivotally connected to apin K passing through the front bolster and axle and is guided also in ashell N fastened between the two cross pieces of the forward hound N andheld from lateral movement by means of pins N 2 passing through saidcross ieces. By the provision of the shell N, saicf forward reachsection H is always held at right angles to the front axle.

O designates a clevis which is fastened to the rear end of the forwardreach section and has a pin O passing through the portion which rojectsrearward of the end of said forward reach section and is adapted to formmeans whereby the plates E upon the rear reach section may be pivotallyconnected to the forward reach section, thereby forming means wherebythe. running gear may be turned about a curve within a small compass. Tothe forward ends of the hound, which is fixed to the forward axle, is adraft bar J pivotally mounted upon the rod J and I designates a tonguehaving a suitable pole tip at one end and near its rear end is provldedan elongated slot L. The arms of the tongue hound are apertured, as atS, for the pur ose of receiving the clamping screws T, which are ada tedto pass through said elongated slot in t e tongue and the nuts T ulponthe ends of said screws are tightened to 0 amp the two arms of thetongue hound with sufficient frictional force against the opposite sidesofthetongue to hold the latter in an adjusted position, accordingly asit may be desired to adapt the tongue for use in connection with horsesof diflerent sizes. For instance, in the event of horses of considerablelength, the tongue would be lengthened out and shortened correspondin 1ywhen used in connection with horses whic are short. In order to protectthe tongue from the parts of the tongue hound which are clamped thereto,any suitable wear plates of metal or other material may be interposedbetween the arms and the sides of the tongue to take up the wear.

A suitable evener W is held to the tongue by means of a pin W passingthrough one or another of the apertures in the tongue. It will be notedthat the pin W, which serves to hold the evener upon the tongue, willalso serve as a means for positively preventing the tongue from movingforward in the event of the same slipping between the clamping arms ofthe tongue hound by said pin coming in contact with one of the clampingscrews,

adapted for use in turning curves within a short compass and, by theprovision of the tongue, the gear may be readily adjusted for use inconnection with horses of various sizes.

What I claim to be new is In combination with the rear axle of therunning gear of a vehicle, a hound connected to said axle, platesfastened to the opposite faces of the forward ends of said hound, an

open ended shell interposed between said p ates and the inner ends ofthe diagonal pieces of the hound, a reach section mounted within saidshell, a bolt passing through registering apertures in said plates,shell and reach section, a forward axle and hound, a forward reachsection pivotally connected to the forward axle, an open ended shellfastened to the forward hound and through which said forward reachsection passes, a 1

space intervening between said reach sections, and links pivotallyconnecting the reach sections, as set forth.

In testimony whereof I hereunto al-llx my signature in the presence oftwo witnesses.

ABRAHAM LIN CON HAMILTON.
